Answer:
The three primary factors affect the injury severity of an electric shock: 1) the amount of current passing through the body 2) the duration of the current flow and 3) the current path through the body.
Weight is equivalent to the product of the mass of an object and the strength of the gravitational field.
Using:
F = ma
a = 8.2 / 5
a = 1.64 N/kg
The gravitational field strength is equivalent to 1.64 N/kg.
